For the first time in 45 years, the government is doing something to reduce the number of illnesses and deaths caused by workplace exposure.
We're talking specifically about crystalline silica. It's a mineral found in everyday materials such as roads and buildings, but it's a known cancer-causing substance.
The new limit from the Occupational Safety and Health Administration is 50 micrograms per cubic meter of air, on average, over an eight-hour shift. The previous limit, in place since 1971, was 250 micrograms for construction and 100 micrograms for other industries.
